ROPE-BUCKLE.

Specification of Letters Patent.

Patented Jan. 25, 1910.

Application filed January 18, 1909. Serial No. 472,833.

To all whom-it may concern:

Be it known that l, SIGVAR'L Kvxn, a subject of the King of Norway,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented a certain new and useful Rope-Buckle, of whichthe I following is a specification.

Theobject of my invention is to provide a I rope buckle of simple,durable and inexpensive construction, in which the buckle is lirmly andsecurely held to the rope when the rope is tightly stretched and inwhich the buckle is prei 'ented from slipping on the rope when the ropeis slack.

A further object is to provide a buckle of this kind in which the buckleis firmly retained on the rope Without the use of springs or othersimilar devices on the tongue.

My invention consists in the construction, arrangement and combinationof the various parts of the device, whereby the objects contemplatcd areattained, as hereinafter more fully set forth, pointed out in my claim,and

illustrated in the accompanying drawings,j

in which Figure 1 shows a plan view of the com plete buckle embodying myinvention. Fig. 2 shows a longitudinal, sectional view of same with arope in position therein. Fig. 3 shows a plan View of a modified form ofmy improved buckle with part thereof broken away to show the swiveljoint. Fig. 4t shows a sectional view on the line 47-4 of Fig. 3, andFig. 5 shows a detail perspective view of the form of tongue used inconnection with the buckle illustrated in Figs. 3 and 4.

Referring to the accompanying drawings, 1

the buckle comprises a body portion or frame which is substantially ovalin shape and is indicated by the numeral 10. The sides of the frame arearched, as clearly shown in Fig. 2, so that the central portion of theframe stands in a plane above the end portions thereof. At one end ofthe frame is a socket 11 and a ring 12 is pivotally connected with thesocket 11 by means of a ball 13 as shown in Fig. 3, to thereby provide aswivel connection between the ring 12 and the frame of the buckle. Oneof the sides of the frame is provided with a rounded portion having lugs14 at the opposite sides thereof. This rounded portion forms a j ournalfor the tongue. The tongue member is indicated by the numeral 15 and isprovided at one end with a collar 16 having a slot 17 therein. The saidcollar surrounds the journal at the side of the frame and a limiting pin18 is extended through the slot 17 and fixed to the said journal. Theother end of the tongue 15 is designed to rest upon the opposite side ofthe frame.

In practical. use and assuming that the buckle is in the position shownin Fig. 2, then the lug is permitted to hang straight downwardly and arope is extended through the ends of the buckle in a substantiallystraight line. Then the portion of the rope between the ends of thebuckle is bent downwardly far enough to permit the tongue to swingupwardly to position resting against the opposite side of the frame.Then when the rope is drawn tight, it will securely clamp the tongue 15against the frame. The parts are so shaped that the tongue will be wideenough to cause the rope to bind against the sides of the tongue and theadjacent. portions of the ends of the frame, as clearly shown in Fig.and the rope will be in position almost in a straight line. Obviously,when the rope is tightly stretched, the tongue will be firmly held inposition and when the rope is slack, it will bind between the sides ofthe tongue and the adjacent portions of the frame in such a manner thatthe rope will not bend dowl'iwardly to any appreciable extent betweenthe ends of the frame, and, therefore, the tongue can not becomeloosened. l.herefore, by providing a buckle in which the tongue isarranged in a plane different from the ends of the frame, it is notnecessary to use a spring for bold ing the tongue in position as therope itself, by binding upon the tongue and frame and by being arrangedin a substantially straight line, will itself hold the tongue inposition without; the use of springs, no matter whether the rope isstretched tight or is slack.

in the moditied form shown in Figs. 3, st, and 5, I have shown a. buckleembodying my invention and especially adapted for use in eonneetimi withflat straps. In this buckle, the parts are proportioned so that a flatstrap may be inserted in the frame and will engage the tongue and frameends in the same manner that rope will engage the form of buckle shownin Figs. '1 and 2. In addi tion. I have provided, on one face of thetongue. a sharpened projection it), which projection will engage theadjacent portion devices it will be strong and durable.

I claim as my invention. An improved rope buckle, comprlsmg asubstantially oblong body portion having arched sides, a tongue pivotedto one of said {sides and designed to engage the concave po1ftion of theother side, said parts being so erases arranged that when the convexportions of the sides are uppermost, the under surface of the tonguewill be in a plane above the upper edges of the ends of the bodyportion, so that a rope may be extended through the buckle, over theends of the body portion, and under the tongue, said rope being inclineddownwardly between the ends of the body portion.
